8PECIPICATION forming part of Letters Patent No. 890,373, dated October 2, 1888.

Application filed June 2, 1888. Serial No. 275,816. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE W. KEELER, of Trenton, in the county of Mercer and State of New Jersey, have invented a new and Improved Sash-Lock, of which the following is a full, clear, and exact description.

The invention has for its object to provide a simple and efficient sash-lock; and it consists of a locking-bar adapted to be pivotally secured to the partingstrip of a windowframe, and adapted, when swung, to be received at one end in a recess or mortise in the upper sash while bearing down on the top rail of the lower sash, the free end of the lever being engaged by a beveled catch-block, as hereinafter more particularly described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both figures.

Figure 1 is a perspective view of a portion of a window frame and sashes with my improvement applied, and Fig. 2 is a vertical section through the meeting-rails of the sashes.

A represents a portion of the side rail of the lower sash; B, the side rail of the upper sash; A B, respectively, the meeting-rails of the lower and upper sashes; O, the parting-strip of the window frame, and I) the stopbead thereof.

At the junction of the side rail, B, of the upper sash and its meeting-rail Bis formed a recess or mortise, I), at the inner side, for receiving the inner end, 6, of a locking-bar, E, which is pivotally secured to the face of the parting-strip C of the wind0w-framc by a screw, F, or otherwise.

To the face of the stop-bead D is secured a beveled catch-block, G, beneath which the outer end, 0, of the locking-bar E is held when the latter is in position to lockthe sashes, the bar lying, as shown, across the top of the meeting-rail of the lower sash, its inner end being received in the recess 1) of the upper sash. In this position the lockingbar E effectually prevents both the lowering of the upper sash and the raising of the lower sash.

When it is not desired to lock the sashes, the end 9 of the locking-bar is sprung out from engagement with the catch block, be yond the same, and brought to the position indicated by dotted lines, whereby it will be out of engagement with both sashes and either of the latter may be freely moved. The meeting-rail A of the lower sash is cutaway, as at a, to allow of its movement past the locking bar.

By forming a vertical series of recesses or mortises, b, in the side rail of the upper sash, the latter maybe lowered to a greater or less extent and locked in the open position. The locking-bar and catch-block will in practice be suitably ornamented.

The device, it will be seen, is of very cheap construction, of neat appearance, and easy of operation, and cannot be released from the outside of the window even by a force greater than the sashes could withstand.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isv The combination, with a window-frame and its sashes, the upper sash having a vertical recess in the inner face of its side rail parallel with the face of the parting-strip between the two sashways, ofa verticallyswinging bar, E, pivoted between its ends to the face of the said partingstrip at the juncture of the meeting-rails of the sashes, the short arm of the bar entering the said vertical recess when the long arm is swung downwardly across the top rail of the lower sash, and the stop G, secured to the window-frame in the path of the said long arm to lock it and both sashes from vertical movement, the said bar, when not in use, lying vertically against the face of the parting'strip, substantially as set forth.

GEORGE KEELER.
